Once upon a time, Mika had a family. Once upon a time, Mika was human. Once upon a time, Mika lost it all.
Upon trying to escape from the underground vampire city, Sanguinem, Mika's family is brutally murdered. The last thing Mika remembers is yelling at Yuu to run. The next thing he knows, he's a vampire. He doesn't know what happened to Yuu, and still doesn't.
But not for long.
*silently creeps onto the vampire Yuu bandwagon*
